Installation
Inspect the units for mechanical damage. Inspect all electrical connectors for bent or damaged
pins and latches. Report any damage to the carrier and to Telecast Fiber Systems, Inc.
Leave the protective plastic caps on the optical connectors until it is time to attach the Þber(s) to
the units. Store the caps in the plastic bag packed with this manual. Place the caps back on the
connectors whenever the Þbers are left disconnected.
Rack Mounted Installation
Units are shipped ready for bench use. To rack mount the units, mounting adapters must be
attached. Each adapter is held in place by two #10 ßat head screws (see Figure 4).
Figure 4. Installing the Rack Mount Adapters
Place the units in their intended locations before attaching any cables or wires. This will prevent
accidental damage to the cables or their connectors.
Fiber Optic Installation
The installer is responsible for providing the Þber optic cable runs which are available from
Telecast Fiber Systems, Inc. Refer to the Accessory List on page 16 of this manual for the cable
and other items required for system installation. Be sure that the Þber core diameters are
compatible with the intended installation distances as shown in Table 1.
The system units have been conÞgured at the factory for the Þber type with which they are going
to be used.
Mark or tag the optical Þbers when they are pulled, carefully avoiding the Þber tip, so that their
identity is known at both ends. If there is confusion about the identity of the two Þbers, illuminate
the end of one Þber with a ßashlight and look for the light at the other end.
